Review Activity # 1

It is the ability to do work and create change.

• force

• energy

• motion

• space

It is defined as the energy flowing from a hotter object to a colder object.

• mechanical

• sound

• heat

• light

It is a special kind of force that acts in the opposite direction as the applied force.

• friction

• motion

• physics

• chemistry

It is a method of heat transfer that happens in solids where they are in direct contact with each other.           

• radiation

• convection

• conduction

• summation

This is the term used for stored energy.

• kinetic energy

• energy

• motion

• potential energy

This is the ability of an organism to produce light.

• bioluminescence

• fluorescent

• analogous

• biomass

These materials allow light to pass through completely.

• transfer

• transparent

• translucent

• radiation

It happens when the surfaces of two objects at rest are in contact with each other.

• rolling friction

• static friction

• kinetic friction

• sliding friction

It comes from electromagnetic radiation produced by burning objects such as fire, the sun, stars and even laser emitting objects.

• light

• heat

• mechanical

• sound

These are light sources found in nature.  

• public sources of light

• natural sources of light

• man-made sources of light

• personal sources of light
